Do you have any links that J-20 use 22 or 14nm ? I am a bit surprised really

Sir I have NO available info regarding the 14nm chip so forgive me BUT as the Chinese had fully indigenized the 14nm process node maybe they have as for the 22nm chip it had been in used since 2020 or earlier.

I don't think military use any chips lower than 14nm ? not sure about F-35, it may use some 7nm chips

Even 90nm would do just fine, power efficiency is not a big deal for military weapons

The F-35 ICP uses modules with two CPUs. The CPUs are Freescale PowerPC 7448s. They are fabbed at 90nm.

The Su-57 uses compute modules where each module either has two 90nm Elbrus-2SM CPUs or four Neuromatrix DSPs. The DSPs are used for things like target recognition AI.

The total amount of orders in hand exceeds 4.6 billion yuan! Shengmei Shanghai's revenue in the first three quarters increased by 78.87% to 86.22%​

This is an important news.

Most of the discussion in the forum is around advanced nodes capabilities of Chinese equipment manufacturers. This makes sense because YMTC / SMIC / etc, have been the main targets in this round of attacks by US.

But it is on mature nodes that China fights the real battle. Mature nodes are the pillars of China mega-industrial complex. Advanced nodes are a "nice to have", legacy nodes are a "must have".

Luckily (but not by luck!) Chinese companies have already successfully localized equipment for mature nodes. Now what is really needed is to scale up tools production. If they have to fill the void left by foreign manufacturers they have to scale 2X 3X production capacity within very short time to reduce the impact in expansion plan of 28nm and above fabs.

What is needed IMO is an industrial mobilization like in war time...because this is a war. In this government could definitely help.

Mostly American bs, but one quote from a YMTC insider
“We’ve been doing everything possible beforehand to support existing production lines, such as stockpiling all kinds of equipment,” said one senior YMTC engineer.

Stockpiling equipment for existing production lines, implying that new production lines don't use stockpiled American equipment?

Deep down they must know that the backdoor thing is a myth. Why do they insist on suffering?

Im not so sure about hardware backdoors being a myth. But in network equipment i'm sure the west should be able to counteract potential remote breaches. Im more surprised they tried to sell your average debugging ports and tools as backdoors that shit is quite damaging for the tech industry in general.

You also have special tooling available to find secret operation codes/assembly instruction to find weaknesses and backdoors. Some years ago i saw a presentation on youtube that did exactly that. Interesting thing is some of these instructions are shared between hardware vendors. Back then after seeing what things like "row hammer" like exploitation could do to privilege escalation and leaking of memory. I just assume if they want to read your shit they are able to do it.

Breaking the x86 instruction set(skip to like 24min to see it in action, section at 31 min is also interesting):

Not only for producing chips but also for purchasing. So Xiaomi wants a 7nm chip? Tough luck, banned.
Lenovo wants the latest Intel 7nm chip? Banned

I mean complete ban for buying any chip <14nm from any Western controlled fab. Not only for AI, but everything

Would that not kill their supply chain as well, in that they can't move production of devices that use those chips out of China fast enough to mitigate the worldwide impacts of such embargo.

I think for China, EVs are much more important than smartphones. After all, EV is a growing market worldwide, whereas smartphone is a mature market with diminishing growth. As long as China can supply the ICs required for EVs independently, China will be OK.

There are from @theorlonator post.:)


Hi guys, this was from an old Nikkei article about China's equipment maker competitors to the global equipment maker competitors. Is there any company missing from this list? Maybe some more knowledgeable posters like @olalavn or @tokenanalyst can answer.

Thanks @ansy1968
Among them which ones that is on par with market leader such as LAM, Applied Material etc?

As I understand, SMEE is not yet on par with ASML.
